Hi: I'm building a small tool on top of LLVM Core Library. ``` LLVMContext context; SMDiagnostic diag; Module *M = parseIRFile(InputIR, diag, context).get(); if (M == nullptr) { diag.print("LLVM", errs()); exit(-1); } assert(M->isMaterialized() && "Module not materialized!"); PointerType *ArrayPtrTy =

What is the proper way to load a set of pre-generated LLVM IR and make it available to runtime JIT modules such that the same types aren't given new names and inlining and const propagation can still take place?   My attempt so far: I compile a set of C functions to LLVM IR offline via 'clang -c -emit-llvm -S -ffast-math -msse2 -O3 -o MyLib.ll MyLib.c' For each runtime JIT module, I

Previously I had asked how to write then read back IR to/from a file. The write code looked like: LLVMContext ctx; SMDiagnostic diag; Module *m = ParseIRFile( "my_file", diag, ctx ); However, the code I'm trying to retrofit LLVM IR into passes me just a std::ostream&. How can I read IR from a std::ostream? I figured out how to use raw_os_ostream to adapt a

Hi All, I am a new member in the group, have been doing some experiments with LLVM IR. I am facing issue with de-compiling the following instruction once it is read, %var2 = call i8 @myfuncCall (i2 %var1) In after I parse the file (lets say using parseIRFiles ). I can see the instructions,( the function call instruction ), How can I get the %var2 from the instruction/callInstruction ? going thru the llvm installations cpp and .h files, it is not clear how do I get the desired variable. Thanks in Advance. regards Tarique -------------- next part -----...

Hello, I am a newbie to LLVM and right now I am on the hook to parse some IR code and do some instrumentations. However, my problem is that no matter how I tweak my parsing code, it simply cannot print out anything. So here is my C code: int your_fun(int arg2) { int x = arg2; return x+2; } And here is my parsing code: #include <llvm/IR/Module.h> #include

I am trying to parse LLVM IR from a bit code file. I went through the following steps. hello.cpp #include <iostream> int main() { std::cout << "Hello world!" << "\n"; return 0;} dump.cpp #include <llvm/IR/Module.h>#include <llvm/IRReader/IRReader.h>#include <llvm/IR/LLVMContext.h>#include <llvm/Support/SourceMgr.h> using

Hello everyone, I wanted to copy a function from one file to another. The file that I wanted to copy the function into contains a function with the same name and same number of instructions. I decided to just replace the instructions with those of the other function. I am doing all of this from within a function pass. *1.* I created a function pass in which I extract a function using

Hi, I am trying to load another bytecode file in one pass. I checked the opt.cpp, it uses following to load a bytecode file: ... LLVMContext &Context = getGlobalContext(); ... SMDiagnostic Err; // Load the input module... std::auto_ptr<Module> M; M.reset(ParseIRFile(InputFilename, Err, Context)); ... My question is in the runOnModule method where I want to load

Hello all, I am trying to use the LLVM libraries to do register allocation on LLVM IR code -- and output IR as the result. There are two problems that arise when we try this : a. The LLVM backend requires that one goes through all the steps sequentially namely -- Instruction selection -- Scheduling and Formation -- SSA-based machine code optimizations -- Register

I am hitting an LLVM assertion from the llc tool iff the bitcode file is optimized at -O3 level by opt). -O1 and -O2 levels of opt do not cause this assert. LLVM version 3.4svn DEBUG build with assertions. Built Jul 14 2013 (15:39:08). Default target: x86_64-unknown-linux-gnu Host CPU: amdfam10 I have attached the input bc file before -O3 optimization :bzip2.del.bc.tgz I have attached

Hi, I am trying to implement a scenario similar to running ExceptionDemo.cpp with parameter -1 (where the JITed code calls the C++ function which throws an exception) Different from the given example I am using IRParser instead of IRBuilder. I can successfully catch the exception in Linux but the program crashes in Mac and Windows. The code is similar to as follows: ### The test.cpp :

Looking at /tools/llvm-link/llvm-link.cpp may give you some ideas here. I havent looked at your specific use case, but llvm-link uses ParseIRFile to pull in a bitcode file and build a Module for it. You can then create a Composite using the Module * and call Linker::LinkModules(Composite.get(), NewModuleToLink.get()... to link a new Module to your Composite Module. -Chris On Feb 14, 2013, at

I did a RelWithDebInfo + asserts build of LLVM just now and, when running "make check" under Valgrind, am seeing a lot of uses of uninitialized memory like the one below. Anyone know offhand what's likely to be the root cause? Unfortunately a Debug build doesn't give these errors. Thanks, John FAIL: LLVM :: Analysis/BasicAA/pr18573.ll (2093 of 18733)

Hi Lang, Thank you for your answer! This helped me again a lot!! Also that ResourceTracker is a really neat feature! Looking forward to it! :3 I changed the title cause… there is another issue I have (sorry about that…) I’m finally allowed to investigate the ORC JIT for integration into our system, which meant I got a few days to actually play around with it. However, another problem arise

Hi, I don't see the LLVM bug I filed (http://llvm.org/bugs/show_bug.cgi?id=16780) making any progress. Can someone suggest me whether the bug is in the correct state? -Milind On Fri, Aug 2, 2013 at 1:29 PM, Milind Chabbi <Milind.Chabbi at rice.edu> wrote: > Hi Hal, > > I have filed http://llvm.org/bugs/show_bug.cgi?id=16780 > > -Milind > > On Fri, Aug 2, 2013 at

Hi everyone, I am writing an application that uses LLVM JIT and I would like to throw an exception from the JIT and catch it in the C++ code that invokes the JIT. This does not seem to work. I've written what is hopefully a super simple demonstration to reproduce this. I would appreciate any help with this. Thank you The demonstration is composed of: 1) thrower.cpp - a source file that

Well, it looks like almost all of the problems go away when I build using trunk instead of 3.9. So, that was scary but I'm going to forget it ever happened. >8000 test cases failed under Valgrind!!
